📄 Description

Describe your changes

Fix IPv6 endpoint parsing in userspace WireGuard

IPv6 endpoints like [2001:aaa:bbb::ccc]:51820 were being incorrectly parsed, causing them to appear malformed as 2001:aaa:bbb::ccc]:51820.

This bug affects debug bundle generation, causing IPv6 endpoint information to be missing from wgshow.txt. The error is non-fatal (logged and skipped), so peer connections still work normally, but troubleshooting IPv6
connectivity issues was more difficult without the endpoint data.
